The GLOW stack — sold as the GLOW Blend — is a three-peptide research combination that brings GHK-Cu, BPC-157 and TB-500 together in a single 70 mg vial. It's the blend most associated with skin, collagen and recovery research, and this page covers what's in the stack, the research areas each component appears in, how it compares to KLOW, and how to source it with full documentation from Australian stock.
What is the GLOW stack?
The GLOW stack is a combination (blend) research peptide — a single lyophilised vial that holds three separately studied compounds in fixed proportions, rather than one. The "glow" name comes from the GHK-Cu component, the copper-binding peptide most associated with skin and collagen research. Each of the three is a well-characterised research peptide in its own right, with its own page in our library; the GLOW Blend simply provides them together in one preparation. It is supplied strictly for laboratory and in-vitro research use.
What is in the GLOW Blend
Each 70 mg vial contains, in approximate amounts:
- GHK-Cu (~50 mg) — a copper-binding tripeptide (glycyl-L-histidyl-L-lysine). Studied in skin-regeneration, collagen-synthesis and tissue-remodelling research. This is the "glow" in GLOW.
- BPC-157 (~10 mg) — "Body Protection Compound 157", a synthetic peptide fragment. Studied in tissue-repair, tendon-healing and angiogenesis research.
- TB-500 (~10 mg) — a Thymosin Beta-4 fragment. Studied in cell-migration, joint-mobility and muscle-recovery research.
These describe fields of scientific study — they are not claims about effects in humans. Nothing here should be read as a statement about what the stack does in a person; NextGen Peptides supplies the GLOW Blend strictly for laboratory and in-vitro research use.
Why a stack instead of separate vials?
Two practical reasons show up in the research context. First, convenience — one reconstitution instead of three. Second, consistency — a pre-measured stack keeps the ratio between the three peptides fixed across a study, rather than relying on mixing three vials separately each time. The trade-off is flexibility: with a blend you can't adjust one component independently, which is why some researchers still prefer single vials. Our guide to the GLOW Blend explained covers that trade-off in more depth.
GLOW vs KLOW
The two are closely related. GLOW is the three-peptide stack (GHK-Cu, BPC-157, TB-500) at 70 mg. KLOW is the four-peptide version — the same three plus KPV — at 80 mg. In other words, KLOW is GLOW with the added anti-inflammatory and immune-signalling angle of KPV. Researchers focused on the skin and recovery strand tend to reach for GLOW; those who also want the KPV component choose KLOW.
Storage & handling
Supplied as a lyophilised (freeze-dried) powder. Because of the GHK-Cu content it carries a blue tint once mixed (from the bound copper) — a clear blue solution is expected. Store at −20°C; refrigerate at 2–8°C after mixing and keep out of light. See our full guide to storing and reconstituting research peptides, what to mix it with in our bacteriostatic water guide, and work out concentration with the reconstitution calculator. Run diluent slowly down the vial wall and swirl rather than shake; never refreeze a reconstituted solution.
Sourcing the GLOW Blend in Australia
We hold the GLOW Blend in Australian stock, so orders placed before the daily cut-off are dispatched same or next business day — no overseas freight, no customs wait. With a combination product, verified identity and purity matter even more than usual: every batch is independently third-party tested, with the Certificate of Analysis published for you to read before you order.

Common questions about the GLOW stack
What is the GLOW stack?
A combination (blend) research peptide — a single 70 mg vial containing three separately studied compounds: GHK-Cu, BPC-157 and TB-500. Supplied for laboratory research use only.
What is in the GLOW Blend?
GHK-Cu (~50 mg), BPC-157 (~10 mg) and TB-500 / Thymosin Beta-4 fragment (~10 mg). Each is covered in depth on its own research page.
What is the difference between GLOW and KLOW?
GLOW is the three-peptide stack at 70 mg; KLOW is the four-peptide version (adds KPV) at 80 mg.
Why is the GLOW Blend blue when reconstituted?
The blue tint comes from the copper bound to the GHK-Cu component, not from any additive — a clear blue solution is expected.
Is the GLOW Blend tested and does it come with a CoA?
Yes. Every batch is independently tested for purity and identity, with the Certificate of Analysis published.
Is GLOW held in Australian stock?
Yes. We hold the GLOW Blend in Australian stock and dispatch same or next business day for orders placed before the daily cut-off.
